Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!

You will need to download and add the appropriate JARs to your project and or your class path, as well as having a database to connect to, unless you are using SQLite in which case the database is local.

MySQL

First up is MySQL connectivity. This first snippet will check you have loaded the JDBC driver correctly.

import java.sql.*;
public class MySqlLoadDriver {
  public static void main(String [] args) {
    Connection con = null;
    try {

      // Load the MySQL JDBC driver
      Class.forName("com.mysql.jdbc.Driver") ;
      System.out.println("MySQL JDBC driver loaded ok.");

    } catch (Exception e) {
      System.err.println("Exception: "+e.getMessage());
    }
  }
}

The following snippet will set up a connection to the database. Where the host in the example is set to localhost so you may change this to point to your database address or tunnel in to your database using a client like Putty. Also change username and password to your database username and password.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class SimpleConnection;
{

     static public void main(String args[])
     {

      Connection con = null;

      try {

         Class.forName("com.mysql.jdbc.Driver") ;
         System.out.println("MySQL JDBC driver loaded ok.");
         con = DriverManager.getConnection(
         "jdbc:mysql://127.0.0.1:3306/","username", "password");
         System.out.println("Connected with host:port/database.");
         con.close();

     } catch (Exception e) {
              System.err.println("Exception: "+e.getMessage());
     }

    }

}

Oracle

Oracle has a two types of connection I have played with Oracle Call Interface and Oracle’s JDBC Thin driver uses Java sockets to connect directly to Oracle. It provides its own TCP/IP version of Oracle’s SQL*Net protocol. Because it is 100% Java, this driver is platform independent and can also run from a Web Browser. Depending on which one you want to use comment out or delete the other line. In the example I am using the OJDBC Thin Driver not the Oracle Call Interface.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class OracleSimpleConnection {

     static public void main(String args[])

     {
         Connection con = null;

         try
         {
               Class.forName ("oracle.jdbc.OracleDriver");
               System.out.println("Oracle JDBC driver loaded ok.");
               con = DriverManager.getConnection(

                   //"jdbc:oracle:oci7:@//localhost:1521/ORCL","username", "password");
                   "jdbc:oracle:thin:@//192.168.104.11:1521/ORCL","username", "password");
               System.out.println("Success!!");
               System.out.println("Connected with host:port/database.");
               con.close();
          }
          catch (Exception e)
          {
               System.err.println("Exception: "+e.getMessage());
          }
       }
}

SQLite

Finally the creation and testing of an SQLite Database, adding in a few things with a simple query.

import java.sql.*;

public class SQLiteTest {

public static void main(String[] args) throws Exception {

    Class.forName("org.sqlite.JDBC");

    Connection conn = DriverManager.getConnection("jdbc:sqlite:test.db");
    Statement stat = conn.createStatement();
    stat.executeUpdate("drop table if exists people;");
    stat.executeUpdate("create table people (name, occupation);");
    PreparedStatement prep = conn.prepareStatement("insert into people values (?, ?);");
    prep.setString(1, "Gandhi");
    prep.setString(2, "politics");
    prep.addBatch();
    prep.setString(1, "Turing");
    prep.setString(2, "computers");
    prep.addBatch();
    prep.setString(1, "Wittgenstein");
    prep.setString(2, "smartypants");
    prep.addBatch();
    conn.setAutoCommit(false);
    prep.executeBatch();
    conn.setAutoCommit(true);
    ResultSet rs = stat.executeQuery("select * from people;");

    while (rs.next()) {
          System.out.println("name = " + rs.getString("name"));
          System.out.println("job = " + rs.getString("occupation"));
    }

    rs.close();
    conn.close();

  }

}

To get the Oracle Driver go toand then to the JDBC Drivers page which at the time of writing is here:

Ensure you have Maven properly setup on your machine.

Navigate to the folder containing the jar in a command line prompt.

Enter the following;
mvn install:install-file -Dfile=ojdbc5.jar -DgroupId=com.oracle -DartifactId=ojdbc5 -Dversion=11.2.0.3 -Dpackaging=jar -DgeneratePom=true

Where:
-Dfile is the path to file
-DgroupId is the group ID
-DartifactId is the artefact ID
-Dversion is the version of the package
-Dpackaging is the package type i.e. jar
- DgeneratePom will automatically generate the pom.xml entry

Note: If you are using Powershell you will need to escape the – with a back tick so -Dfile=ojdbc5.jar becomes `-Dfile=ojdbc5.jar`
If you are adding Sun JARs is there is a helpful article on naming conventions to use here.

Ok, so for whatever reason you have entered your little pattern too many times on your Android phone and you are now locked out. You can’t remember your pattern, something or someone else entered it too many times or something of the like and you are now stuck at the “Too Many Pattern Attempts” screen. The phone is demanding the Google account details that you synced the phone with when you very first turned it on. Maybe you have now forgotten those login details too or the phone is simply refusing to accept the correct login details.

For whatever reason you are at a dead end and stuck at the too many pattern attempts page of doom, however, all is not lost. Far from it my dear reader! If you simply want to get rid of the pattern lock you which you are stuck trying to remember, but aren’t yet completely locked out, you are in luck.

Firstly note that;

• Removing your battery and SIM or just the battery will NOT solve your problems
• A hard reset will solve your problems; however, it will erase ALL personal data from your device. You will be able to download your applications from the store again, and sync  all of your contacts again from Google but all texts and personal data that is not synced or backed up externally, say on to your memory car, WILL be lost.
• Using Android Debug Bridge (adb) will only disable the pattern lock if you are not already locked out completely and at the too many pattern attempts page of doom.

So What Can You Do?

• Enter your email address in to the device
• In the password field enter “null” without the speech marks.
• You will then be prompted to enter a new pattern and once again you have your phone back in action with all data intact.

That Didn’t Work, What Now?

• There are reports that if you have uppercase letters in your email address and or password that trying again with them in lower case will work.
• If you have got USB Debugging already enabled on your device, and you are not quite at too many pattern attempts page of doom then you can disable the pattern lock via adb.

How to Disable Pattern Lock via ADB

• You must have previously enable USB Debugging (Settings -> Application -> Development -> USB Debugging)
• Download and extract the Android SDK (from here)
• Plug your phone into your computer
• In command line navigate to where you extracted the SDK, then to the Tools folder which should contain adb.exe

Do not simply run adb.exe but instead enter adb –d shell. Your command prompt should look like the following;

ADB Instructions

• Now disconnect and power off your phone, and turn it back on and the pattern lock should be gone.

What If I Didn’t Have USB Debugging Enabled?

I hate to say it but you are more or less at the end of the road.

A factory reset is probably your only option.

This guide is using Excel 2007.

Select the cell which has the fill you require, then in the Home ribbon select the fill icon, and click on More Colors…

In the Colors dialogue select the Custom tab. Take a note of the RGB code for the fill of the cell. So in the screen shot the RGB is 255,204,153.

Now you need to convert the RGB value to Hexadecimal. I would recommend using http://www.endprod.com/colors/rgb2hex.htm but you can always Google for a different converter.

Now with your Hex value you need to format it ready for input into Excel. The simple explanation is that for Excel you need to build a String to enter as the BackColor property.

The String will start with &H00 followed the Hex you just generated. However, you need to swap the last two characters of the hex string with the last, so if your Hex code is ffcc99 then you need to use 99ccff. So, now you have your string &H00*****, where the asterisks are replaced with your Hex code add a final & to the string and you are now ready to go.

Return to Excel, in the Developer tab on the Ribbon (to add Click the Microsoft Office Button, and then click Excel Options. Click Popular, and then select the Show Developer tab in the Ribbon check box) click on the Design Mode icon. Now single click on the CheckBox you want to change the color of and then in the Properties box enter your new color string in the BackColor, or if it is for the text color enter the string into the ForeColor property.
